There is no cheap way of doing leaf removal and being efficient. Cheap is a rake and a tarp. You have to design a set up based on your equipment at hand and methods that are available to you. Leaf disposal is a big issue in a lot of areas.
I had an old cyclone rake that came with an old riding mower that I bought years ago, worked good for a 3.5hp unit. They are designed more for riding tractors and on site dumping.
